The custom trailer wiring harness for your 2018 Toyota Highlander with the tow package is part # HM11141825; however, it's only a 4-way connector.

To get a 7-way on your Highlander start with the # HM11141825 4-way and then use our # ETBC7 kit to convert it to a 7-way. The kit plugs into the already installed 4-way for the lighting funtions and includes all of the wiring needed for the additional functions.

I've linked a video from when we installed the # ETBC7 kit on a 2014 Highlander with a brake controller. The process is basically the same as with your 2018 since the kit is a universal part.

It sounds like you are just needing the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole #37185. This will plug right into the 4-Way flat on your tow vehicle and provide a 7-Way to connect with your trailer. Since you are only needing to power the lights…
